fuel gauge PLEASE HELP!!!

[e30power7931]

that is what my gauge is displaying

[accident]

how do you know you're at 1/2 tank?

[e30power7931]

when i fill up the gauge goes to full. when the low fuel light comes on i am at half a tank and the range meter usually says about 155 miles to go but falls every few feet and also when i fill up it will say about 450+ miles which i know is very unaccurate

[accident]

The OBC isnt very acurate. Please explain your fuel gauge issues better.

Sorry if this is in the wrong section..im new.....my 87 325is has a strange gas gauge. bare with me im gonna explain lol. When i reach half a tank im empty and the light comes on.....i have replaced the fuel sender numerous times and checked the ground and tried other working gauges but nothing helps....when i hit empty i can only add 12 gallons tops.....im so confused. PLEASE HELP ME!! lol...Has anyone ever even seen this happen before? even my master technition who has worked on e30s and e28s forever is stumped....once again Thanks!

How big do you think your gas tank is? IIRC the e30 tank is between 14.5-16.5, and if you're hitting gas light and putting in 12 gallons it sounds like you're pretty on par.
